  • Study of the dynamic forces acting on steel structure during gyration motion of slewing cranes
    Jerman, Boris, strojnik, 1967- ; Kramar, Janez, strojnik, 1940-
    ǂThe ǂvibrations and sway of the load at slewing cranes are caused mainly by the gyration motion of the jib around the vertical axis and by radial movement of the load suspension point. In the paper ... only gyration motion of a jib that produces a space motion of the pendulum is considered because has been much less investigated than translation of the suspension point. The objective is to investigate the dynamic forces acting on the crane's steel structure. Therefore a non-linear mathematical model of the load sway is set up. A non-linear nature of the swinging motion for large angles and non-linearity of power transmission is considered. The structure's elasticity, friction, damping of materials and air resistance are also taken into account. The effects of various types of inputs on the trajectory of the suspended load are also studied. For confirmation of the mathematical model a physical model of a crane was built and measurements were carried out.
